Mobile social networks, as a type of delay‐tolerant networks, are composed of nodes with different social properties in which information can be shared among them through opportunistic links. In such networks, it is important to analyze social properties of mobile nodes for transmitting information because they lack a stable source‐to‐destination delivery path and connect intermittently. Many social‐aware routing algorithms have been proposed to address these problems. However, these algorithms fail to achieve an optimal performance since they ignored an important social property, social identity. In this paper, we propose a social identity–aware opportunistic routing algorithm by considering social identities and social influences of mobile nodes in mobile social networks. It is shown that the social identity–aware opportunistic routing algorithm substantially improves the routing performance compared with the existing algorithms according to the simulation results in 2 real‐world human contact traces.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
